I recently purchased a 1991 Red NSX. Among other things already installed on the car is a Tubi exhaust serial #00092. It needed adjusted badly and had an exhaust leak on the drivers side, so I read up about them here on prime. What I found was:
1) The installer left out the gaskets.
2) The Tubi pipes required dremel work to mate with the cat properly.
Thanks to prime I knew to check the mate between the cat and muffler pipes and that some Tubi's required dremel work in that spot. It seals much better now, but not perfect because I still need the gaskets, and it's still crooked but sits a little better. If bending hangers doesn't fix it I'll have a muffler shop heat and bend the pipes a little.
